Zoology - Human Health and Diseases Question with Solution | TestHub

Cancers of the internal organs are mainly detected by the use of techniques like radiography (use of X-rays), CT (computed tomography) and MRI (magnetic resonance imaging).
CT: It uses X-rays to generate a three-dimensional image of the internals of an object.
MRI: It uses strong magnetic fields and non-ionising radiations to detect the pathological / physiological changes in the living tissue.

ELISA is used to detect AIDS.
